The present invention is .adapted to be employed in furnis for use in opening containers of varicus characters. In the drawings I have illustrated two forms of the invention employed in opening typical containers of the character commonly employed to package powdered, granular and ilaked products. It .is te be understood that the invention is not to be construed as limited or restricted to the speciilc forms or applications about to be described but is to be taken as including any features or modifications that may fall within the scope of the claims.

The container illustrated in Figs. 1 to 4, inclusive, of the drawings may be considered a `substantially rectangular container formed of paper, cardboard, or other fibrous materiai. The container shown in Figs. 1 to 4, inclusive, of the drawings includes'a wall I0 and a wail Il, as weil as its various other walls. The wall I is of a singie thickness of paper or cardboard while the wall II may be of two or more thicknesses, as illustrated.

rlie embodiment of the present invention illustrated in Figs. 1 to 6, inclusive, of the drawings, includes, generally, a body I2, a cutter or -punch I3 on the body I2 adapted to be forced through a wall I0 of the container C, a cutter I4 on the body I2 adapted to enlarge the opening made by the punch I3 to form a discharge opening in the container, and means I5 on the body I2 for removably holding the device on. the container C.

The body I2 carries the punch I3, the cutter I4 and the means I5 and is adapted to serve as a pouring spout for the container C. The body I2 may be formed of any suitable' or desirable material. In the particular case illustrated in the drawings the body I2 is formed of sheet metal. In the preferred construction the body I2 is substantially U-shaped or channel shaped in transverse cross section having spaced side anges I6 and a main wall or web I1 extending between and connecting the flanges I6. The flanges I6 are flat and substantiaiiy parallel and are at substantially right angles to the flat wall or web I1. The outer face or surface of the web I1 forms a convenient part engageable by the user for forcing the cutter I4 through a wall of the container C as will be hereinafter described. An apron I8 is provided at one end of the wall cr web I1. 'I'he apron I8 may be an integral continuation of the web I1 and is at substantially right angles to the web and the flanges I6. The apron I8 projects bei-'ond the outer edges I9 of 'the flanges I6. The body I2 just described may be a simpie, inexpensive, one piece element.

The punch I3 is provided to form a starting opening or relatively small opening 2liv in a wall of the container C to receive the entering end of the principal cutter I4. 'Ihe punch I is carried by the body I2 so that the body orms a guide for positioning and guiding the punch. In the form of the invention being described the punch I3 is carried by the wall or web I1. The punch I3 may be varied considerably in character without departing'from the invention. In the particular case illustrated in the drawings the punch I3 includes a foot or base 2| secured to the wall or web I1 as by welding. A part 22 projects laterally or outwardly frpm the base 2I in or adjacent the plane of the apron I8 and carries a piercing or cutting part 23. 'I'he cutting part 23 of the punch I3 ls spaced outwardly from and is substantiaily parallel with the body web I1. In the simple form of the invention illustrated the punch I3 is an integral part formed of sheet metal or the like. The cutting part 23 of the punch is fiat and has side edges 24 converging to a point 24. The point 24* is spaced a considerable distance from the outer or open end of the body i2. When the punch I3 is to be used the body I2 is positioned with its wall or web I1' against the Wall II of the container C and the device is pressed or moved to the position illustrated in Fig. l of the drawings .causing 'the cutting part 23 to pierce the wall III.

Thus the body web I1 and the root 2| on the web operate to guide the cutting part 23 to make the starting opening in the wall I0 at a given or definite distance from the container wall II.

'Ihe cutter I4 is adapted to be pressed or forced through a wall ef the container C to form a discharge or pouring opening 24. It is preferred to press or force the cutter I4 through a side wall of the container or a container wall i'ormed c-f one thickness of material or cardboard. The cutter I4 is rigidly secured to the body I2 to project laterally therefrom. The cutter I4 includes a main part 25 and flanges 26 extending along the opposite edges of the main part 25. In practice the cutter I4 may be formed of sheet metal and its main part 25 may be fiat. The main part 25 of the cutter I4 lies in a plane at substantially right angles to the plane of the body web I1 and is spaced inwardly from the apron I8. 'I'he anges 2,6 project from the main cutter part 25 to have their outer edges at or engaging the inner side of the apron I8. The apron I8, the main cutter part 25 and the anges 26 define or form a substantially rectangular passage 21 for discharging or conveying the contents from the interior of the container C as will be hereinafter described. The flanges 26 may continue inwardly beyond the end of the main cutter` part 25 and may be welded or otherwise secured to the body iianges I6 to attach the cutter i4 to the body A reinforcing projection or brace 28 may be provided on the apron I8 and may be welded or otherwise secured to the outer face of the main cutter part 25 to as sist in securing the cutter I4 to the body I2 and to lenti rigidity to the construction.

The main part 25 of the cutter I4 continues outwardly beyc-nd the fianges 26 and its projecting portion has edges 29 converging outwardly to a point 30. The edges 29 and the point 30 are suitably sharpened to readily enter and cut the container wali. The point 30 of the cutter I4 is adapted to enter the opening 20 or to pierce a wall ci' the container C and the cutting edges 29 are eiective in enlarging the opening entered or started by the point 30. It will be apparent how the pointed and sharpened main cutter part 25 is operable to cut a straight elongate slot. In accordance with the invention the edges 3l of the flanges 26 are inclined and sharpened to make lateral cuts at the opposite ends of the slot formed by the part 25 and to aid in bending back the tab or fiap F dei'lned by the slot and cuts. Following the formation of the elongate opening or slot by the main cutter part 25 continued inward pressure on the device brings thesharpened edges 3| in contact with the container wall to make lateral cuts therein and bend the ap F inwardly. The brace 28 is preferably inclined and engages the ap F to assist in bending the flap inwardiy. The brace 28 is spaced between the nges ''S and is located above or outwardly from the plane of their edges 3| to contact the ap F between its ends alter the wall III has been cut by the edges 3|. This engagement of the brace 28 with the ap is eiective in bending the ap inwardly to leave the opening 24 unobstructed. The opening 24 thus formed by the cutter I4 is substantially rectangular and unob- Structed. When the device is positioned and used as illustrated in the drawings the opening 24 has its outer side immediately adjacent the wall of the container and the flap F is bent backwardly against or parallel with the wall I I by the anges 26.

The edges I9 of the body anges I6 are adapted to engage the wall I of the container C to limit the inward movement of the cutter I4` The body wall or web I1, the anges I6 and the container wall I0 dene a longitudinal opening or passage 32. The outer end of the passage 32 is open and the inner end of the passage 32 communicates with the passage 21. It is important to note that the passages 21 and 32 are angularly related, that is, the passage 32 extends at substantially right angles to the passage 21. The communicating passages 21 and 32 are operable to discharge measured or substantially definite quantities of material from the container C as willv be hereinafter described.

The means I is provided to releasably or removably hold the device on the container C in the position illustrated in Figs. 2, 3 and 4 of the drawings where the cutter I4 projects through the opening 24 and the flanges I6 bear on the container wall I0. The means |5.includes one or more punches 33 on the body I2 for piercing the wall I 0 of the container to hold the body I 2 against outward shifting and displacement. In the case illustrated in the drawings there is one punch 33 on each body flange I6. The punches 33 project laterally or inwardly from the edges I9 of the flanges I6 and are preferably provided adjacent the outer ends of the anges. The punches 33 may be separately formed parts suitably secured to the anges I6 or may be integral with the flanges I6 as illustrated in the drawings. The punches 33 are pointed, having outwardly converging edges 34 joining at relatively sharp points 35. The punches 33 are preferably twisted or spiralled to be more effective in preventing displacement and undesirable movement of the device with respect to the container C. The thrust or pressure applied to the body I2 to force the cutter I4 through the wall of the container C also forces the punches 33 throughthe container wall.

In operating or using the form of the invention4 illustrated in Figs. 1 to 6, inclusive, of the drawings, the device may be held by the user or operator in a position where the base 2| and the bodv web I1 engage the wall II of the container and the punch I3 is spaced above the container wall I0. The device is then moved relative to the container C to force the punch I3 through the container wall I0. It will be noted that the engagement ofthe base 2| and the web I1 with the container wall Il locates or positions the punch I3 to form the starting opening 20 a denite distance from the wall II. Following the cutting of the starting opening the device is moved relative to the container C to disengage the punch 23 from the opening 20. The device is then held or positioned where the point portion of the cutter I4 is entered in the starting opening 20 and the body I2 is spaced above the container Wall I0 with its web I1 spaced from and substantially parallel with the container wall I0. A downward or inward pressure is then applied to the device. The body wall or web l1 presents a convenient upper surface againstwhich the users hand may be pressed to apply the necessary 'force to the device. The downward or inward pressure on the device forces the cutter I4 into the opening 20 so that its cutting edges 29 enlarge or lengthen the opening. As the downward or inward movement oi the device continues the edges 3| of the flanges 26 engage and cut through the wall I0' forming lateral cuts at the opposite ends of the slot made by the main cutter part 25. The edges 3| also bend back the flap F. The continued downward or inward movement of the device relative to the container C also forces the punches 33 through the container wall I0. A simple inward or downward pressure on the device thus forms the discharge opening 24 in the wall |0 and forces the punches 33 through the wall to removably secure the device on the container.

Following the cutting of the opening 24 and the attachment of the device to the container C as above described, the container may be manipulated to discharge substantially denite quantities of its contents through the passages 21 and .32. To discharge a denite amount of the contents from the container C, the container is rst moved or swung to a position where its wall II faces substantially downward, as shown in Fig. 3. During the movement of the container C from the position shown in Figs. 1 and 2 to the position shown in Fig. 3 a substantially denite quantity of its contents spills or pours onto the passage 21. The container C is then moved to a position Where its wall I!) is facing downwardly and is inclined and where the outer end of the pasasge 32 faces downwardly, as shown in Fig. 4. This movement of the container C allows the substantially Adenite quantity of material that has spilled into the passage 21 to discharge or pour outwardly through the passage 32. If it is desired to obtain additional material from the container C the container may be alternately moved between the positions where the material pours into the passage 21 and discharges from the passage 32. A substantially denite quantity of the contents of the container C is poured into the passage 21 and then discharged through the passage 32 during each complete oscillation or cycle of movement ol the container C and the user may readily obtain as much of the contents as needed. The container C may normally rest in the position shown in Fig. 3 and the desired quantities of the contents may be readily obtained by alternately tilting it between this position and the pcsiticn shown in Fig. 4. It is to be noted that an excessive cr unwanted quantity of material cannot spill or be poured from the container when thedevice is in position on the container. When the container is emptied or when it is desired to remove the device from the container the flanges I6. or the flanges I5 and the apron I8 may be readily grasped and the device detached frcm the container by withdrawing the cutter I4 and the punches 33 from their respective openings.

The form of the invention illustrated in Figs. 7 to 10 of the drawings comprises, generally, a body 4|), a cutter 4I for forming an opening in a wall |01* of a container C1, a guide 42 on the body and means 43 for detachably retaining the device on the container C1.

The body 40 may be identical with the body I2 l the length of the body web 44. The guide arm described above. As 'shown in the drawings the body 49 comprises a main wall o r web 44, flanges 45 extending along the edges of the webv 44 and an apron 46 projecting from one end of the web 44. The -flanges 45 are at substantially right angles to the web 44 and the anges 45. The body may be a 4simple one pie or integral member.

The cutter 4| is provided to form an unobstructed discharge opening 41 in a wall IIIEof the container C1. The cutter 4| may be identical with the previously described cutter I4. 'I'he cutter 4| includes a fiat main part 4'8 projecting from and disposed at substantially right angles to the body 40 and side parts or ilanges 49 on the part 48. The cutter part 48 has sharpened ycut- `ting edges 50 converging downwardly or Aoutwardly to a point 5I. 'I'he cutting edges 50 and the point 5I are suitably sharpened to readily' cut through the wall of the container. The-cutter 4I is rigidly attached or secured to the body 40. lProjecting end portions 52 of the flanges 49 may be secured to the body flanges 45 at 53 by welding or the like. The outer edges of the flanges 49 abut or are adjacent the apron 45 whereby the cutter part 48, the flanges 49 andi the apron 45 define a passage 54. -The outex ends or edges of the flanges 49 are inclined and sharpened to constitute cutting edges 55. The cutting edges 55 are operable to engage and cut through the wall IIIn of the container to make lateral cuts at the ends of the cut formed by themain cutter part 48 and to bend back or inwardly the flap F1 dened by the cuts; The action or operation of the cutter 4| just described is substantially the same as that of the cutter |4.

The guide 42 is provided on the body 40 toi guide the cutter 4| to 'form the dischargefpp'ening 41 in the desired location.1 In`tl1e sirn"1fille` form of the invention illustrated, the guide4.21533.`

The arm 55 may be secured to the body wall or web 44 by weldingat 58. In practice the arm 45 may extend throughout 51 of the guide 42 is a iiat part disposed :itsubstantially right angles to the body 40. 'I'he guide-'- arm 51 is of substantial length and in practiceprojects outwardly or downwardly beyond the pointed end of the cutter 4I. The guide arm 51 is positioned to engage a second wall Il of the I container C1 to position the cutter4| a definite distance from the wall I |a and to guide thectter 4| to form the discharge opening 4 1 as desllred. k 'I'he means 43 for removably securing the device to the container C1 may-be identical with the above described means I5. In the embodiment of the invention being described the means 43 com- I prises a'pu'nch 50 projecting from the edge 52 lof each body'ange 45 adjacent-the outer end ofthe flange.

When the edges |52 of the body flanges are in engagement with the container wall Ill, the body web 44, the

flanges .4 and the container wall |0`define a pas'- sage or channel 53 which communicates with and which is at substantially right angles to the passage 54.

In Figs. 11 and 12 of the drawings I have shown an elementy arranged in the form of the invention illustrated in Figs. 7 to 10, inclusive, of the drawings, which element is operable to control or vary the amount of material discharged from the container C1.

or both forms of the invention ormay be removed or omitted, if desired. In the drawings I have shown it embodied in the type of the invention illustrated in Figs. 7 to 10, inclusive, of the drawings, -it being understood that it may be used or supplied with eitherform of the invention.

'I'he element 10 is optional, that is,

it may be employed with or embodied in either one 104 The element 10 operates to limit the amount of the material discharged from the container C1 during each discharging manipulation. or each cycle of movement-of the container for discharginglits contents. The element 10 is'a'valve-like part or elementand may be formed of a strip or band of sheet metal or the like. 'Ihe element 1I! is substantially U-shaped in plan elevation, having two spaced side parts 1I and a transverse part 12 extending between and connecting the parts 1 I. 'I'he connecting part 12 is stepped or provided with shoulders 13 adjacent its connection with -arn'is'or sideA parts 1I bearing against the inner Sides kitthe body anges`. 45 and with its connecting-.part 12 adjacent'or-bearing' against the apron 45. the element 1|Iis' in this position the recess 14 has one side closed by the body web 44 and -has its opposite side open to receive material from the passage 54; The mouth of the recess 14 isopenfto the body channel 53.

The container C1 may then be moved or swung to aposition where its wall ll1 faces substantially downwardly, in which position a substantially dcnitc quantity of material is free to spill into the passage 54 and the inner end of the passage 83. The container C1 is then moved to a position where its wall llln faces downwardly and is inclined and the open end of the channel or passage 63 faces downwardly. With the container `in the last mentioned position the substantially definite quantity of material previously spilled into the passage 54 is free to ow out through the channel or passage B3. The container C1 may be alter nately moved between the position where material is free to flow into the passage 54 and the position where the substantially definite quantity of material is free to discharge from the channel 63. In this manner the user may obtain the needed or required quantity of material from the container C1 without danger of the discharge of an excessive amount of material from the container. When the container C1 is empty or when it is desired to remove the device from the container the body anges 45, or the body flanges I and the guide arm 51, may be grasped and the device readily moved relative to the container C1 to disengage the cutter 4| and the punches 6U from their respective openings.
